What is a Dummy load?

A dummy load is an electronic component used to simulate a real operational load. It is commonly used during the testing of power supplies, amplifiers, and transmitters, where it applies a load to the circuit to ensure proper operation. Dummy loads are particularly important in amplifier testing and during the development phase of electronic equipment. They have resistance values similar to real loads, which allows for accurate performance evaluation without overloading the circuit. Dummy loads are also used in durability tests, quality control, and troubleshooting.

Application of Dummy load

✅ Amplifier testing
Dummy loads are used to test the performance of amplifiers without using actual speakers during audio equipment development.
✅ Power supply testing
Dummy loads are used to apply a load to power supplies to verify their output.
✅ Troubleshooting
Dummy loads are used to apply load to circuits to help identify issues during equipment troubleshooting.
